What otherwise innocuous word is used casually that you can’t stand? Perhaps make a list of words you don’t like, pick one and write about it.
(Sidebar: I have a list on my phone of words I do not like, and another list of words that I really like. Top of the like list? Resilient. Defenestration. Ostensibly. Top of the dislike list? Raiments. Physicality. Munch.)
